    Re: micrometer sextants.

    Hello Brad,
    
    thanks for your response. Actually this was meant as a contribution to the
    "primacy question"; just to add a little tidbit of information of who did
    (advertized) what (drum micrometer) when with which arguments. In my opinion
    it doesn't matter who claims a certain accuracy - and for that matter: in
    which country the company was situated - the interesting question is when
    there was a practical shift in the employment of a  certain technology - or
    improvements on a known technology.
    
    Regards,
    Wolfgang
